基于PPC4 E数字式压力控制器的压力仪表自动检定/校准技术研究

摘要

An automatic measurement method for pressure meter verification / calibration is developed on base of the PPC4E digital pressure controller. It has been proved by the experiment. The results show that verification / calibration of the pressure meter can be completed automati-cally, and the verification certificates and the original records can be generated automatically, which greatly improve the measurement accuracy and efficiency of the measuring data of pressure in flight test.%基于PPC4 E数字式压力控制器，利用LabVIEW软件开发平台，实现压力仪表自动检定/校准，并通过实例进行了验证。本方案实现了压力仪表自动检定/校准、证书自动生成及记录自动创建等功能，极大的提高了压力仪表的检定/校准效率和测量准确度，保证了飞行试验中压力测量数据的准确可靠。
